MATERIAL PROPERTIES OF STEEL AND CONCRETEREPORT FROM LABORATORY DEMONSTRATIONS ON 17 MARCH 2017AS PART OF THE UNIT OF STUDY CIVL2201 STRUCTURAL MECHANICSABSTRACTThis report describes a tension test on a steel coupon, and a compression test on a concrete cylinder. Theprimary objective of the tests was to obtain the stress-strain curves for the two materials. Both test methodsare described.It was found that the steel first exhibited elastic behaviour until the tensile load increased to 438 MPa, afterwhich it experienced plastic deformation. It had a yield stress of 438 MPa, an ultimate tensile strength of 562MPa, an elastic modulus of 213 GPa, and a uniform ultimate strain of 19%. The concrete had an ultimatestrength of 33.9 MPa, an elastic modulus of 33.3 GPa and a strain at failure of 0.236%.These results reveal the disparity in strength, stiffness and ductility of steel and concrete. When comparing thetensile strength of steel to the compressive strength of concrete, steel is the superior material in all qualities,having a much higher ultimate strength and strain at failure. In particular, steel is much more ductile, whileconcrete is brittle, with a very low strain at failure.
